The growth of federal regulations over the past six decades has cut U.S. economic growth by an average of 2 percentage points per year, according to a new study in the Journal of Economic Growth. As a result, the average American household receives about $277,000 less annually than it would have gotten in the absence of six decades of accumulated regulations—a median household income of $330,000 instead of the $53,000 we get now.

So if the effects of regulation are so deleterious to economic growth and the prosperity of citizens, why do countries enact so much of it? Dawson and Seater’s paper mentions three theories: Arthur Pigou’s notion that governments enact regulations to improve social welfare by correcting market failures, George Stigler’s more cynical view that industries capture regulatory agencies in order exclude competitors and increase their profits, and Fred McChesney’s argument that regulations are chiefly aimed at benefiting politicians and regulators. I asked if their results fit most closely with McChesney’s. Dawson replied: “This could be the conclusion that one reaches based on our empirical results (since they show a net cost of regulation over time), but again we did not set out to prove or disprove any particular theory.” Seater added that their research does not address the question of “why society allows excessive regulation….It’s an important [issue], but it is one for the public choice people to study, not for macroeconomists like me and my coauthor.”
